MEANS FOB, INCINERATING REFUSE.

Application led March 28, 1923.

To all whom t may concern:

Be it known that I, HARRY L. CowLns, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Means for Incinerating Refuse, of which the following is a specification.

This invention relates to means for incinerating refuse and its main object is to provide means for the above purpose that are of greater eliiciency and economy than those commonly in use. In certain of the incinerators for refuse which areV now on the market it is a feature to use a small grate at the lower -p-art and under the grate to place a burner, also to employ a plurality of small pipes extending from the grate to one side of the same, and then to extend said pipes upward to remove the waste gases from the burner without utilizing such gases above said grate. In my improved incinerating means I mak-e use of such gases in ydrying the mass of refuse in the greater lpart of the container therefor and pass the hot gases from the gas or other burner or other suitable source perpendiculary upward along the side or sides and ends of said mass until it is dry enough to ignite. After which the combustion of the material itself aids the drying of the portion of the mass further removed from the flaming portion, and such 'drying is still further assisted by the hot gases and flame from the burner or burners until all the refuse that is combus-A tible is reduced to ashes.

In connection with the improved method I have also devised novel means for carrying out the same efficiently and economicallyy as will appear in the description of said means in detail hereinafter. The means I prefer to employ to accomplish the above objects together with other features of my improved means of incinerating refuse, are illustrated in the ydrawings accompanying and forming part of this specification, Vand in which Figure 1 is a vertical section through one form of my invention taken on the line 1 1 of Figs. 2 and 3. l

Fig. 2 is a vertical section taken on the line 2 2 of Figs. 1 and 3.

Fig. 3 is a horizontal section on the line 3 3 of Figs. 1 and 2.

Like characters of reference refer to like parts in all the figures ofthe drawings.

Serial N0. 628,195.

In the form of my invention illustrated in Figs. 1 to 3 inclusive, the numeral 2 indicates an upri ht casinor for the incinerating means and wliich preferably consists of an outer portion or wall 3 and an inner portion or wall 4 which is preferably supported by an angle member 5 secured to the outer wall 3. Ordinarily a lining 6 of refractory material such as lire brick is suitably supported inside of the wall 4 as by means of the member 7 For holding the refuse for incineration I preferably employ a container such as indicated by 8 in the various figures of the drawings and in the form illustrated in the first three figures the container is formed of L-shaped metal bars such as 9 suitably supported. Preferably the supporting means for said bars take the form of metal bars such as 10 and 11 at the upper parts and bars 12 at the lower parts of the L-shaped bars 9. The bars 10 an'd 11 are supported in any suitable way such as by angle members 13 secured to the wall 4, and the bars 12 preferably are supported by resting them on a portion of the lining 6. v In Figs. l and 3 two containers 8 are employed which are separated by a flue 15 kwhich also extends -around the ends of the containers so as to form a Vcapita-l letter H in the horizontal section. The bars 9 have openings 16 between them which openingsv at their upper parts communicate with the flue 15. Any suitable .means for drying and igniting the refuse in the'containers 8 may be employed but preferably I employ a flame which will play against the bottom part of the container, and I allow the hot gases from said flame or hot gases and flame also to pass up the flue 15 acting on the sides or side and also on the ends of the mass of refuse similarly as on the bottom of the same. Ordinarily I employ a burner adapted to burn fluid fuel such as illuminating gas or the like and the flame from the burner is directed against the bottom of the container 8 and it acts first to dry and finally to ignite the refuse through the openings 16, and the hot gases from the burner, or a portion of the flames together with the hot gases pass up said flue and dry the sides or sides and ends of the mass through the openings 16 between the bars 9, the gases finally passing out of the flues 15 laterally through the openings 17 and over the top of the refuse, and thence to the outlet pipe 18,.

In the drawings 2O indicates the burner and 2l refers to the piping therefor and 22 is the mixer for mingling air with the gas supply. Ordinarily 1 provide a pan 2e under the burner or burners to catch ashes and any water which drips down from the rei'use. rlhere is a door 25 in the casing 2 through the doorway of which the pan can be removed and the contents emptied. For placing the refuse in the incinerator l have provided a lid or top door 27 suitably hinged to the casing 2 at 28, and over the flue l5 have provided portions 29 and 29 to prevent the refuse from falling down into the ue l5 when charging the incinerator. rllie portions 29 and 29 have a further function of deflecting the gases and flames laterally over the top ot the refuse in the containers 8.

The method of inc'inerating consists in drying the refuse along one or more sides or ends of the mass of refuse by means of a stream of hot gases passing upward, also in drying the bottom portion of the mass by the flame from the burner passing through openings in the container which opeiiiings are also made to continue up along the flue or are made opening into the flue to expose the refuse to the action of the hot gases and flame. The llames and gases are then deflected laterally over the top of the refuse. rllhe mass is then ignited by the flames from the burner through the openings in the container bottom and the ignition continues upward into the flue along the sides and ends of the mass. Drying of the interior of the mass is now effected by the burning mass together with the hot gases and llame first applied and incineration continues until all the mass that will burn is reduced to ashes.

lVhat 1 claim is l. The combination of a rectangular casing, two refuse compartments: supported on opposite inside wall faces of said casing, rectangular in plan, having a common flue between them, and flues at each end connected to the first-mentioned one, the side and end walls of each of said con'ipartments being composed of a multiplicity of substantially vertical bars joined at their upper ends to a horizontal U-shaped bar, and the bars forming the sides next to the common flue beingl E -shaped at the lower part and joined at the bottom to a horizontal bar resting on the casing wall, the lower portions of the bars of the two end walls in each compartment joined to the two end l shaped bars respectively, heating means under said retuse compartments, and a roof over the tops of the flues inclined towards said compartments.
